14. Dynamical Astronomy
A treatise on celestial mechanics in the tradition of Newton's Principia.
Here Laplace applied his analytical mathmatical theories to celestial bodies
and concluded that the apparent changes in the motion of planets and their
satelites are changes of long periods, and that the solar system is in all
probability very stable. He gave methods for calculating the movements of
translation and rotation of heavenly bodies and for resolving problemsof
tides, from which he deduced the mass of the moon.
